After installing an update of Henshin, I cannot open my transformation anymore!

How can I use dynamic EMF with Henshin?

Define your Ecore models as usual. Make sure you use set the namespace URIs and prefixes for all packages. To use the packages in Henshin, right-click in the Henshin editor and select Import Package -- From Workspace and choose the packages from your Ecore files. To create an dynamic instance model, right-click on an Ecore file and select Henshin -- Create Dynamic Instance. This will create an XMI file which you can then edit in the Sample Reflective Model Editor of EMF.

Does Henshin support automatic tracing for exogenous transformations?

Henshin follows a rewrite approach. Tracing is not build into the transformation language but can be easily realized using a generic Henshin Trace Model.
